04-16-2012

TORONTO, April 16, 2012

NorthWest Value Partners Inc. (“NorthWest”) today has announced that it has received the unanimous
support of the Board of Trustees of GT Canada Medical Properties REIT (TSX-V: MOB.UN) (“GT Canada”)
to make an offer to acquire 100% of the trust units (the “Units”) of GT Canada at a price of $2.05 per Unit in
cash (the “Offer Price”). The Offer Price is subject to anti-dilution adjustments based on the results of the
GT Canada rights offering announced on March 12, 2012 (the “Rights Offering”). If pursuant to the Rights
Offering no rights are exercised, the Offer Price will remain at $2.05 per Unit, whereas if 100% of the rights
are exercised, the Offer Price will be adjusted to $1.87 per Unit. Northwest’s offer is conditional upon at
least 66 2/3% of the Units (on a fully-diluted basis) being validly deposited under the offer and not
withdrawn. Full details of the offer will be included in the formal offer and takeover bid circular that will be
mailed to GT Canada Unitholders. The offer represents a premium of 61.4% to GT Canada’s closing Unit
price on April 13, 2012, and offers all GT Canada Unitholders a liquidity event.

Following successful completion of the foregoing transaction, NorthWest will sell GT Canada’s existing
portfolio of eleven medical office buildings all of which are located in Ontario, as well as a 25,313 square
foot fully leased medical office building in Port Hope, Ontario, the acquisition of which GT Canada intends to
close on May 1, 2012 (collectively, the “GT Canada Portfolio”) to NorthWest Healthcare Properties Real
Estate Investment Trust (“NorthWest Healthcare Properties REIT”) (TSX: NWH.UN) for $87.3 million, which
represents a valuation consistent with the NorthWest offer to GT Canada unitholders.

Following the sale of the GT Canada Portfolio to NorthWest Healthcare Properties REIT, NorthWest intends
to reconfigure GT Canada to support its international healthcare real estate initiatives, which currently
include significant investments in Australia / New Zealand, Brazil and Germany.

Peter Riggin, CEO - NorthWest Healthcare Properties REIT, stated “We are excited about this prospective
transaction, since the GT Canada properties are all multi-tenant medical office buildings that are a strategic
fit with our portfolio. It is rare that the opportunity exists to purchase a portfolio of medical office buildings,
and we are pleased to be able to do so to further solidify our presence in the important Ontario market.”

GT Canada’s Portfolio will consist of twelve medical office buildings located in central and southern Ontario,
comprising approximately 280,000 square feet of rentable area and over 170 tenants. The buildings are
approximately 98% leased and are all specialized medical office buildings, with almost all of the tenancies
being healthcare related. The leasing profile of the GT Canada Portfolio is similar to the NorthWest
Healthcare Properties REIT portfolio in terms of average tenant lease term and average minimum net rent.

The purchase price payable by NorthWest Healthcare Properties REIT for the GT Canada Portfolio will be
satisfied by the assumption of approximately $49.5 million of mortgage debt, the issuance of NorthWest
Healthcare Properties REIT units to GT Canada (at GT Canada’s option) and by cash funded from internal
NorthWest Healthcare Properties REIT resources. The acquisition is expected to close in the third quarter
and be accretive. The acquisition and potential issuance of NorthWest Healthcare Properties REIT units to
GT Canada is subject to TSX and other regulatory approvals.
